A friend of mine at work rode a BMW on a 45 mile each way commute. I'd pull up to him on my Kymco Bet&Win 250 each day and I'd be wearing my hi-vis yellow vest. He'd be dressed as a "real" motorcycle rider in all black. 8) Then one day he was wearing a bright hi-vis vest himself and I asked him why. He said he watched as a large black Labrador was hit about 9 times on the freeway at night. No one saw the poor dog till it was too late. :shock: He got to thinking how that could be him.
The nice part about reflective tape (or reflectors like the one on this thread), is they don't require any electrical source. If a car is in the area, it will provide the light. In about a month, the rain will be coming down consistently. The commute will be in the dark, or close to it. And even in the daylight, the road and sky will be just shades of grey with grey road spray to cause everything in front of you to disappear. I do everything I can to make sure I can be seen. In well over 60,000 miles of commuting these past few years, I haven't had hardly any cases where there was a close call, or I even had to grab the brakes hard. So it must work.
